VG248 - 1.3(x)

VG248 versions 1.3(x) and earlier are affected.

Problem Description

New U.S. Daylight Savings Time rules go into effect in March 2007. Consequently, the logs and clock on the VG248 may appear one hour off.

Background

On August 8, 2005, the Energy Policy Act of 2005 (H.R.6.ENR) was signed into law. Section 110 of this Act modified the time change dates for Daylight Saving Time (DST) in the US. Beginning in March of 2007 and beyond, DST will begin on the second Sunday of March at 2 AM and end the first Sunday of November at 2 AM.

For more information, see the Energy Policy Act of 2005 (Section 110).

The old DST policy dictated the start of DST was the first Sunday of April and ended on the last Sunday of October.

Problem Symptoms

The time shown in the following locations may be an hour off between the new and old DST start and end dates in 2007:

-March 11 to April 1 in 2007

-October 28 to November 4 in 2007

  1. The clock on the VG248 user interface

  2. Timestamps shown in system logs

  3. Caller ID timestamp shown on analog phones connected to a VG248

Workaround/Solution

The VG248 receives its clock from the Cisco Unified CallManager. Please upgrade the Cisco Unified CallManager server to an appropriate software version based off of the CallManager field notice.

To ensure the new clock is pulled from the Cisco CallManager immediately, please reboot the VG248 after the CallManager is patched.
